Abstract
There is provided a telescoping boom system for an excavating apparatus which includes a linkage member having a pivot segment and lever segment pivoted about a rotating fixed boom. A first hydraulic cylinder is coupled from the fixed boom to the pivot segment. A second hydraulic cylinder is coupled from the lever segment to a retractable outer boom. The first hydraulic cylinder extends to rotate the pivot segment away from a proximate end of the fixed boom, thus forcing the lever segment to rotate towards the proximate end of the fixed boom. The second hydraulic cylinder retracts and combines with the extension force of the first hydraulic cylinder across the linkage member to provide a retraction force to the outer boom.
Claims14
An excavating apparatus for excavating a surface, said apparatus comprising:
- a vehicle base having at least one wheel means integrated with the vehicle base and at least one operating platform having a longitudinal and a latitudinal axis;
- a boom support member disposed adjacent to said operating platform;
- a telescoping boom supported by said boom support member, said telescoping boom including a fixed boom, said fixed boom having a longitudinal axis, said telescoping boom further including an outer boom which retracts and extends within said fixed boom, said outer boom also having a longitudinal axis which is coaxial to the longitudinal axis of said fixed boom;
- a first rotation means for rotating said fixed boom radially about its longitudinal axis;
- a second rotation means for rotating said telescoping boom radially about the latitudinal axis of said at least one operating platform;
- at least one first displacement member coupled at a first end to a member selected from the group consisting essentially of the boom support member, fixed boom, a pivot plate and the operating platform, said at least one first displacement member including a housing and a retractable extension member;
- a linkage member pivoted to said fixed boom at a fixed pivot, said linkage member including at least one pivot segment, wherein said at least one pivot segment includes a distal end and a pivot end, wherein said distal end of said pivot segment is directly connected and pivoted to said retractable extension member of said at least one first displacement member, and wherein said pivot end is fixed in space with respect to the fixed boom, said linkage member further including at least one lever segment;
- coupling means for coupling said at least one lever segment to said outer boom;
- an operating implement connected to a distal end of said outer boom;
- and
- control means for controlling the operating platform, the at least one first displacement member, the operating implement, the first rotating means and the second rotating means.
A telescoping boom system for a excavating apparatus, wherein said excavating apparatus includes a construction vehicle having at least one wheel means integrated with a vehicle base and at least one operating platform, said at least one operating platform including a longitudinal and latitudinal axis, said telescoping boom system comprising;
- a boom support member disposed adjacent to said at least one operating platform;
- a telescoping boom supported by said boom support member, said telescoping boom including a fixed boom, said fixed boom having a longitudinal axis, said telescoping boom further including an outer boom which retracts and extends within said fixed boom, said outer boom also having a longitudinal axis which is coaxial to the longitudinal axis of said fixed boom;
- a first rotation means for rotating said fixed boom radially about its longitudinal axis;
- a second rotation means for rotating said telescoping boom radially about the latitudinal axis of said at least one operating platform;
- at least one first displacement member coupled at a first end to a member selected from the group consisting essentially of the boom support member, fixed boom, a pivot plate and the operating platform, said at least one first displacement member including a housing and a retractable extension member;
- a linkage member pivoted to said fixed boom at a pivot, said linkage member including at least one pivot segment, wherein said at least one pivot segment includes a distal end and a pivot end, wherein said distal end of said pivot segment is directly connected and pivoted to said retractable extension member of said at least one first displacement member, and wherein said pivot end is fixed in space with respect to the fixed boom, said linkage member further including at least one lever segment;
- coupling means for coupling said at least one lever segment to said outer boom;
- an operating implement connected to a distal end of said outer boom;
- and
- control means for controlling the operating platform, the at least one first displacement member, the operating implement, the first rotating means and the second rotating means.
